WATER TEMPERATURE ADJUSTMENT
Safety, energy conservation, and hot water capacity are factors to be
considered when selecting the water temperature setting of the water
heater. Water temperatures above 125°F can cause severe burns or death
from scalding. Be sure to read and follow the warnings outlined on the label
pictured to the left. This label is also located on the water heater near the
top of the tank.
The chart shown above may be used as a guide in determining the proper
water temperature for your home.
DANGER
There is a Hot Water SCALD Potential if the water
temperature thermostat is set too high. Households with small
children, disabled or elderly persons may require a 120°F (49°C) or
lower thermostat setting to prevent contact with “HOT” water.
WARNING
Hot water can produce 3rd degree burns in less
than 6 seconds at 140°F (60°C) and 30 seconds at 130°F (54°C).

SAFETY CONTROLS
The water heater is equipped with a combination
temperature sensor and high limit Energy-Cut-Off
control (ECO) that is located above the upper heating
element in contact with the tank surface. If for any
reason the water temperature becomes excessively
high, the high limit control (ECO) breaks the power
circuit to the heating element. Once the control opens,
it must be reset manually. Resetting of the high
limit control should be done by a qualified service
technician.
CAUTION
The cause of the high temperature
condition must be investigated by a qualified
service technician and corrective action must be
taken before placing the water heater in service
again.
CAUTION
Ensure power is completely
removed from appliance before servicing, as utility
switching devices may falsely indicate that power
has been removed.
To reset the temperature-limiting control:
1. Turn off the power to the water heater.
2. Remove the upper heating element cover and
insulation.
The thermostat protective cover should not be
removed.
3. Press the red RESET button.

Operating Instructions
Water Heater Capacity and Increasing Temperature
Setpoint (For Water Heaters without an Integrated
Mixing Valve):
The water heater temperature setting strongly impacts
the amount of usable hot water available for showers
and baths.
• Energy consumption/savings and efficiency testing of
water heaters is performed according to Department
of Energy (DOE) requirements specified at the date of
manufacture.
• Safety regulations require a factory setting no greater
than 125°F (52°C) for all new water heaters. Therefore,
if your old water heater was set to a hotter temperature
than your new water heater with a factory set setpoint of
120°F (49°C), the new water heater may seem to provide
lower capacity than your old water heater. This can be
corrected by increasing the temperature setpoint.
• If more hot water capacity is desired, increasing the
temperature from 120°F to 135°F (49°C to 57°C) will
enable the same tank of hot water to last about 25%
longer because less hot water is mixed in at the shower
or faucet.
• Increasing the water temperature setpoint may improve
the cleaning performance of dishwashers and washing
machines.
• The user can adjust the temperature setting to meet
their needs. Always read and understand the safety
instructions contained in the owner’s manual before
adjusting the temperature setpoint.
Mixing Valves
• For models with an integrated electronic mixing valve,
hot water capacity can be increased by changing
capacity selection from control, while maintaining outlet
water temperature. See page 9 for instructions to
increase hot water capacity.
• If your model does not include an integrated Electronic
mixing valve: a supplemental mixing valve for reducing
point-of-use water temperature by mixing hot and cold
water in branch water lines are commercially available.
Contact a licensed plumber or the local plumbing
authority for further information.
Extended Shutdown Periods
If the water heater is to remain idle for an extended
period of time, the power and water to the appliance
should be turned off and the water heater drained to
conserve energy and prevent a buildup of dangerous
hydrogen gas. This unit has no power button, power
can only be shut off at the circuit breaker or disconnect
switch. Unplug 120V water heater at power cord outlet
connection.
The water heater and piping should be drained if they
might be subjected to freezing temperatures.
After a long shutdown period, the water heater’s
operation and controls should be checked by qualified
service personnel. Make certain the water heater is
completely filled again before placing it in operation.
NOTE: Refer to the Hydrogen Gas Caution in the
Safety section (see page 3).

Operation Modes
OPERATION
This water heater defaults to the Hybrid operating mode.
To select available modes listed below:
▪ Press the MODE button until the LED next to the
desired Operating Mode is illuminated.
▪ For Hybrid and Heat Pump (Turtle) mode, Press “Enter”
to activate selected mode.
▪ For High Demand Mode (Rabbit), Std Electric and
Vacation Mode, Input the total days to remain in Mode
by pressing + or - and then Press “Enter” to activate
selected mode and operating days.
Note limitation of operating days in each mode as
follows:
▪ High Demand (Rabbit): Default is 3, with a max.
of 99 days.
▪ Std Electric: Default is 3, with a max. of 99 days.
▪ Vacation: Default is 7, up to 199.
In Heat Pump (Turtle), Hybrid or High Demand (Rabbit)
Mode, the corresponding Mode LED will flash anytime
the heating elements are active, such as during the initial
recovery from a large draw. This is normal and does
not indicate an operating issue. The Display will toggle
between the days remaining and the temperature set
point in High Demand (Rabbit), Std Electric and Vacation
Modes.
Cold Climate Efficiency
This heat pump water heater is compliant with the
Northwest Energy Efficiency Alliance Advanced Water
Heater Specification (latest 8.1 version , active at time
of product listing), and may qualify for rebates in some
regions. Check with your local utility for available rebates
and requirements.
A ducting kit is available for use with your heat pump
water heater if desired. [See GEAppliances.com for
ducting kit details].
Ducting kits may be installed to achieve directed flow
of inlet and outlet air for heat pump operation, or to
allow water heater installation in rooms less than 700cu.
ft.(19.8 cu.m.) or without louvered doors, as specified in
the installation instructions.
Heat Pump Mode (Turtle LED) —
RECOMMENDED FOR MAXIMUM SAVINGS
Heat Pump is the most energy-efficient mode for this
water heater. It takes heat from the surrounding air to
heat the water. The time it takes to heat the water is
longer in this mode, so it may not be sufficient if you
have a high-demand situation such as a large household
or company.
Hybrid Mode (LED between Turtle and
Rabbit)
Hybrid mode combines the energy efficiency of Heat
Pump with the recovery speed and power of the Electric/
Standard mode in most water usage situations. Hybrid
mode will allow the unit to perform like a standard
electric water heater while providing significant energy
savings.
NOTE: Energy Guide unit performance, energy
consumption and savings are based on non-ducted
installations in Hybrid mode at required Department of
Energy (DOE) test conditions. Operating in Heat Pump
mode may provide a greater savings in energy and
operating costs than the claimed savings.
High Demand Mode (Rabbit LED)
This mode may be necessary if your household has
a higher-than-average water usage or the unit is
undersized for the household water demands. In this
mode, the unit will use the electric heating elements only
when the water demand rate is high. When using the
heating elements, the water temperature will recover at
a faster rate but it will use more energy to heat it. Unlike
Electric/Standard mode, it will use the heating elements
only when needed, and use the heat pump when water
demand rates are lower.
NOTE: The difference between Hybrid mode and High
Demand mode is that in High Demand mode the heating
resistive elements are activated sooner than in Hybrid
mode. At the end of the selected time period, the unit
will switch back to the previously selected more energy-
efficient mode.
Standard Electric Mode
This mode uses only the upper and lower heating
resistance elements to heat the water, stopping the cool
air discharge during heat pump operation. The time it
takes to heat the water is less in this mode, but it is the
LEAST energy-efficient mode.
At the end of the selected time period, the unit will switch
back to the previously selected more energy-efficient
mode.
Confirm by
pressing Enter
Press
Mode Select
49-6000330 Rev. 1 9
Operation Modes
When activated this feature stores water at higher
temperatures. As hot stored water leaves the tank, cold
water is mixed in to maintain the desired set point. This
mixing allows more usable hot water to be available.
The water heater defaults to Normal hot water Capacity
setting, which is used to calculate annual operating cost,
(and a 125F outlet water setting).
To change tank Capacity setting:.
1. Press the “Capacity” button until High, X-High or
Normal text is illuminated.
2. Confirm selection by pressing “Enter” key.
Capacity Options (based on 120°F default outlet water
temperature setting and 58°F inlet water temperature):
Normal: No increase of hot water capacity from outlet
water setting
High: Increases hot water capacity up to 40%
X-High: Increases hot water capacity up to 60%
Hot Water Flexible Capacity Selection (on some models)
OPERATION
Vacation Mode
This feature is recommended when you will be away from
the home for an extended period of time and hot water is
not needed. In this mode, the unit will reduce the water
temperature setting to 50ºF (10°C) and will use the most
efficient heating mode to conserve energy while the heater
is sitting idle. The unit will automatically resume heating
one day before your return, so that hot water will be
available.
For example, if you will be gone 14 days, set Vacation
mode for 14 days using the steps above. The temperature
setting will automatically reduce to 50°F (10°C) for 13
days. At the end of the 13th day, the previous operating
mode and temperature setting will reset to ensure hot
water is available upon your return.
Extended Shutdown Periods
If the water heater is to remain idle for an extended period
of time, the power and water to the appliance should be
turned off and the water heater drained to conserve energy
and prevent a buildup of dangerous hydrogen gas. This
unit has no power button, power can only be shut off at the
circuit breaker or disconnect switch.
If the water heater has an anode depletion sensing feature
(some models) and the water heater cannot be drained,
it is recommended to leave the power turned on with the
water heater in vacation mode to ensure that the feature
will continue to operate properly while still conserving
energy.
The water heater and piping should be drained if they
might be subjected to freezing temperatures.
After a long shutdown period, the water heater’s operation
and controls should be checked by qualified service
personnel. Make certain the water heater is completely
filled again before placing it in operation.
NOTE: Refer to the Hydrogen Gas Caution in the
Safety section (see page 3).

Routine Preventive Maintenance
DANGER
Risk of Scald - Before manually
operating the relief valve, make certain no one will
be exposed to the danger of coming in contact with
the hot water released by the valve. The water may
be hot enough to create a scald hazard. The water
should be released into a suitable drain to prevent
injury or property damage.
NOTE: If the temperature and pressure-relief valve
on the hot water heater discharges periodically, this
may be due to thermal expansion in a closed water
system. Contact the water supplier or your plumbing
contractor on how to correct this. Do not plug the
relief valve outlet.
Properly maintained, your water heater will provide years
of dependable trouble-free service. It is suggested that
the following annual preventive maintenance program be
established.
1. Inspect Temperature & Pressure Relief Valve.
2. Inspect heating elements, ECO, and wiring to each.
3. Drain and Flush the water heater tank.
4. Anode rod must be removed and inspected.
Temperature and Pressure-Relief Valve:
Once a year, it is recommended to lift and release the
lever handle on the temperature and pressure-relief
valve, located on the front-right side of the water heater,
to make certain the valve operates freely. Allow several
gallons to flush through the discharge line to an open
drain.
Heating Elements and ECO:
Once a year, it is recommended to inspect the heating
elements, high limit Energy-Cut-Off (ECO) control,
and wiring to each. Inspection should be completed by
service personnel qualified in electrical appliance repair.
Most electrical appliances, even when new, make some
sound when in operation. If the hissing or singing sound
level increases excessively, the electric heating element
may require cleaning. Contact a qualified installer or
plumber for inspection.
Draining and Flushing the Water Heater
CAUTION
Risk of Shock - Shut off power to
the water heater before draining water.
DANGER
Risk of Scald - Before manually
operating the relief valve, make certain no one will
be exposed to the hot water released by the valve.
The water drained from the tank may be hot enough
to present a scald hazard and should be directed to
a suitable drain to prevent injury or damage.
A water heater’s tank can act as a settling basin for
solids suspended in the water. It is therefore not
uncommon for hard water deposits to accumulate in the
bottom of the tank. To clean the tank of these deposits,
it is recommended to drain and flush the water heater
tank once a year. To drain the water heater, follow these
steps:
1. Turn off power to the unit. The electric heating
elements will become damaged if operated without
water.
2. Attach a garden hose to the drain valve located at the
bottom of the unit and direct that hose to a drain.
3. Turn off the cold water supply.
4. Admit air to the tank by opening a hot water faucet or
lifting the handle on the relief valve.
5. Open the drain valve. Use a flat blade screwdriver to
turn stem of drain valve.
Flushing the Tank:
1. Follow steps above to drain the water heater.
2. Once the water heater is empty, with the drain valve
open and garden hose attached to the drain valve,
turn on the cold water supply.
3. Allow several gallons to flush through the drain valve
and hose to an open drain.
4. Turn off the water supply and allow any water
remaining in the tank to drain.
5. Repeat steps 3 and 4 until water runs clear.

Cleaning the Filters
In the Hybrid, Heat Pump, and High Demand modes, the
water heater pulls air through the 3 filters and out the back
of the unit. The filters are in place to protect the evaporator
from dirt and dust.
Clean air filters are important to get the highest efficiency.
Occasionally these filters will need to be cleaned. When the
filters require cleaning, the Filter LED will illuminate and an
alarm will sound.
NOTE: If the filters gets too dirty, the unit will automatically
switch to Standard Electric mode and energy savings will
be lost.
Leave the power on. Remove the filter from the top of the
unit and the (2) filters from the side of the unit. Once they
have been removed, the filters can be vacuumed or wiped
clean with a damp cloth or rinsed with warm water.
Once the filters have been cleaned and dried, they can be
replaced by aligning with the shroud and snapping in place
by pushing at embossed locations on filters as shown in
illustration.
After the clean filters have been reinstalled, press and
hold the Reset button (below the FIlter LED), until the
Filter LED turns OFF. The unit will automatically revert
to the previously selected operating mode. If a heating
cycle is active when the filter alarm is reset, it will continue
in Electric/Standard mode to finish the cycle, then
automatically revert to the previously selected mode.
IMPORTANT: Filters must be cleaned when the alarm is
displayed. A dirty filter will make the system work harder
and result in a reduction of efficiency and possible damage
to the system. In order to get the best energy efficiency
available, make sure your filters are clean.
NOTE: If the dirty filter alarm returns within a few days
after cleaning and resetting, it may be an indication of a
refrigerant leak. Further diagnosis by a service technician is
necessary.

Care and Cleaning
Clearing the Condensation Drain Tube
The main drain is intended to carry all condensate away. If
it is clogged, the heat pump will stop operating, the display
will show F73, and an alarm will sound. Press any button
to silence the alarm, then clear the condensate drain by
removing any drain lines and connections, and clearing
debris. Reattach drain lines and connections, then allow
the water heater to run. The GeoSpring water heater will
continue to produce hot water using the backup resistance
heating elements until the condensate drain has been
cleared, and is able to drain properly. Once the drain has
been cleared, the unit will then be able to operate the heat
pump again.
Periodically inspect
the drain lines and
clear any debris that
may have collected
in the lines.
See Installation
Instructions for more
information.
Water Leak Notification & Reopening
Shut-Off Valve
When the sensor detects a water leak (H20 is shown
on display), an audible alert will sound, and a leak alert
notification will be sent to your mobile device (when
connected to the SmartHQ App). If a smart water shut-off
valve is installed, it will stop any new water from being
supplied to the water heater and display will toggle between
“Off” and “H20”. To clear the leak alert, remove the sensor
from the leak source and dry sensor. The display will stop
showing “H20” and “Off” and the valve will open, restoring
water flow to the water heater.

Anode Rod
Anode rods are designed and installed to protect and
extend the life of residential water storage tanks.
The anode rod must be removed from the water heater’s
tank and inspected annually, and replaced when more
than 6” (15.2 cm) of core wire is exposed at either end of
the rod.* NOTE: Artificially softened water will cause the
anode rod to consume more rapidly.
Due to shock hazard and to prevent accidental water
leaks, this inspection should be done by a qualified
servicer or plumber, and requires that the electric power
and cold water supply be turned off before servicing the
anode rod.
NOTICE: Do not remove the anode rod from the water
heater’s tank except for inspection and/or replacement,
as operation with the anode rod removed will shorten
the life of the glass-lined tank and will void warranty
coverage.
Some areas have water conditions that may cause
an odor to develop in the water heater. Special alloy
replacement rods are available to address this condition.
*NOTE: Failure to replace the anode rod when
consumed voids the warranty for the tank. Warranty
coverage for all other components remains intact,
and is unaffected by this maintenance requirement.
The replacement anode rod, and the inspection for
consumption are not covered by warranty.
Additional information for models with an
anode depletion sensing feature (Anode
LED on the control, on equipped models):
When the depletion-sensing anode rod nears
end of life, the ANODE text will illuminate and
the control will beep and display F70. When
this occurs, the anode rod must be inspected
and replaced if the core wire at the top of the anode rod is
exposed.* It is recommended to replace the anode rod as
soon as possible to ensure that the tank will continue to be
protected from corrosion. Call installer/servicer to order or
to replace the anode rod. (See page 15 for instructions to
change the anode rod.)
Press the Anode “Hold To Reset” button (below the Anode
LED) once to silence the alarm. Once replaced, reset the
alarm by pressing and holding the “Hold To Reset” button
for 5 seconds until the control beeps and the Anode LED
will turn off.
If special alloy anode rod is installed to address a water
odor condition, the anode depletion sensing feature must
be disabled. If disabled, annual inspections of the anode
rod are required since the water heater will no longer be
capable of alerting for a depleted anode rod.
To disable the feature:
1. Upon power-up following a special alloy anode rod
installation, the control will sound an alarm and F41 will
display. Press the Anode “Hold To Reset” button to quiet
the alarm.
2. Press the Anode “Hold To Reset” button 3 times. “Off”
or “On” will display confirming that the feature has been
disabled/ enabled.
To enable the feature if a new anode depletion sensing
anode rod is installed, follow Step 2 above.
NOTE: If the display is blank, press any button to wake the
control before entering a button combination.
NOTE: If the water heater has been installed with a
device that periodically cuts power to the water heater, the
accuracy of the anode rod depletion sensing feature may
become compromised and anode rod inspection every 2-3
years is required.
If the water heater will be inactive for a long period of time
and the water heater cannot be drained, it is recommended
to leave the power turned on with the water heater in
vacation mode to ensure that the feature will continue to
operate properly while still conserving energy.
NOTE: Refer to the Hydrogen Gas Caution in the Safety
section (see page 3).

Information on servicing (cont)
– No person carrying out work in relation to a REFRIGERATING SYSTEM which involves exposing any pipe work
shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible
ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation,
repairing, removing and disposal, during which refrigerant can possibly be released to the surrounding space.
Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no
flammable hazards or ignition risks. “No Smoking” signs shall be displayed.
– Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or
conducting any hot work. A degree of ventilation shall continue during the period that the work is carried
out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the
atmosphere.
– Where electrical components are being changed, they shall be fit for the purpose and to the correct
specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. If in doubt,
consult the manufacturer’s technical department for assistance.
– The following checks shall be applied to installations using FLAMMABLE REFRIGERANTS:
• Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be
corrected.
– Repair and maintenance to electrical components shall include initial safety checks and component inspection
procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to
the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to
continue operation, an adequate temporary solution shall be used. This shall be reported to the owner of the
equipment so all parties are advised.
– Initial safety checks shall include:
• That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;
• That no live electrical components and wiring are exposed while charging, recovering or purging the system;
• That there is continuity of earth bonding.
Repairs to sealed components, intrinsically safe components
– Sealed electrical components shall be replaced.
– Intrinsically safe components must be replaced.
– Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of
refrigerant in the atmosphere from a leak.
Cabling
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other
adverse environmental effects. The check shall also take into account the effects of aging or continual vibration
from sources such as compressors or fans.

REQUIREMENTS FOR OPERATION
Requirements for Operation, Service and Installation of Appliances Using
Flammable Refrigerants
Detection of flammable refrigerants
– Under no circumstances shall potential sources of ignition be used in the searching for or detection of
refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used.
– The following leak detection methods are deemed acceptable for all refrigerant systems.
• Electronic leak detectors may be used to detect refrigerant leaks but, in the case of FLAMMABLE
REFRIGERANTS, the sensitivity may not be adequate, or may need re-calibration. (Detection equipment
shall be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential source of ignition and
is suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the
refrigerant and shall be calibrated to the refrigerant employed, and the appropriate percentage of gas (25 %
maximum) is confirmed.
• Leak detection fluids are also suitable for use with most refrigerants but the use of detergents containing
chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work.
NOTE: Examples of leak detection fluids are:
- bubble method,
- fluorescent method agents.
– If a leak is suspected, all naked flames shall be removed/extinguished.
– If a leakage of refrigerant is found, all of the refrigerant shall be recovered from the system, or isolated
(by means of shut off valves) in a part of the system remote from the leak. Removal of refrigerant shall be
according to the manual.
Removal and evacuation
– When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures
shall be used. However, for FLAMMABLE REFRIGERANTS it is important that best practice be followed, since
flammability is a consideration. The following procedure shall be adhered to:
a) safely remove refrigerant following local and national regulations;
b) purge the circuit with inert gas;
c) open the circuit by cutting.
– A non-sparking, adequately sealed or intrinsically safe vacuum pump shall be used.
– The outlet for the vacuum pump shall not be close to any potential ignition sources, and ventilation shall be
available.
– The refrigerant charge shall be recovered into the correct recovery cylinders if venting is not allowed by local
and national codes. For appliances containing FLAMMABLE REFRIGERANTS, the system shall be purged
with oxygen-free nitrogen to render the appliance safe for FLAMMABLE REFRIGERANTS. This process might
need to be repeated several times.
– Compressed air or oxygen shall not be used for purging refrigerant systems.
Charging procedures
– In addition to conventional charging procedures, the following requirements shall be followed.
• Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or
lines shall be as short as possible to minimise the amount of refrigerant contained in them.
• Cylinders shall be kept in an appropriate position according to the instructions.
• Ensure that the REFRIGERATING SYSTEM is earthed prior to charging the system with refrigerant.
• Label the system when charging is complete (if not already).
• Extreme care shall be taken not to overfill the REFRIGERATING SYSTEM.
– Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. The system shall
be leak-tested on completion of charging but prior to commissioning. A follow up leak test shall be carried out
prior to leaving the site.

Decommissioning
– Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment
and all its detail. It is recommended good practice that all refrigerants are recovered safely. Prior to the task
being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of
recovered refrigerant. It is essential that electrical power is available before the task is commenced.
a) Become familiar with the equipment and its operation.
b) Isolate system electrically.
c) Before attempting the procedure, ensure that:
• mechanical handling equipment is available, if required, for handling refrigerant cylinders;
• all personal protective equipment is available and being used correctly;
• the recovery process is supervised at all times by a competent person;
• recovery equipment and cylinders conform to the appropriate standards.
d) Pump down refrigerant system, if possible.
e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the
system.
f) Make sure that cylinder is situated on the scales before recovery takes place.
g) Start the recovery machine and operate in accordance with instructions.
h) Do not overfill cylinders (no more than 80 % volume liquid charge).
i) Do not exceed the maximum working pressure of the cylinder, even temporarily.
j) When the cylinders have been filled correctly and the process completed, make sure that the cylinders and
the equipment are removed from site promptly and all isolation valves on the equipment are closed off.
k) Recovered refrigerant shall not be charged into another REFRIGERATING SYSTEM unless it has been
cleaned and checked.
Labeling
– Equipment shall be labeled stating that it has been de-commissioned and emptied of refrigerant. The label shall
be dated and signed. For appliances containing FLAMMABLE REFRIGERANTS, ensure that there are labels
on the equipment stating the equipment contains FLAMMABLE REFRIGERANT.

REQUIREMENTS FOR OPERATION
Requirements for Operation, Service and Installation of Appliances Using
Flammable Refrigerants
Recovery
– When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good
practice that all refrigerants are removed safely.
– When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are
employed. Ensure that the correct number of cylinders for holding the total system charge is available. All
cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (i. e. special
cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure-relief valve and associated
shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before
recovery occurs.
– The recovery equipment shall be in good working order with a set of instructions concerning the equipment
that is at hand and shall be suitable for the recovery of all appropriate refrigerants including, when applicable,
FLAMMABLE REFRIGERANTS. In addition, a set of calibrated weighing scales shall be available and in good
working order. Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using
the recovery machine, check that it is in satisfactory working order, has been properly maintained and that any
associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult
manufacturer if in doubt.
– The recovered refrigerant shall be processed according to local legislation in the correct recovery cylinder,
and the relevant waste transfer note arranged. Do not mix refrigerants in recovery units and especially not in
cylinders.
– If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable
level to make certain that FLAMMABLE REFRIGERANT does not remain within the lubricant. The compressor
body shall not be heated by an open flame or other ignition sources to accelerate this process. When oil is
drained from a system, it shall be carried out safely.
REQUIREMENTS FOR OPERATION
49-6000330 Rev. 1 23
NOTE: The heat pump operating range is 35°F to
120°F (2°C to 49°C). If the ambient temperature is
outside of this range, the heat pump will turn off and
the electric elements will be used until the ambient
temperature returns to within the operating range.
CAUTION
Risk of Property Damage - The
water heater should not be located in an area
where leakage of the tank or connections will
result in damage to the area adjacent to it or to
lower floors of the structure. Where such areas
cannot be avoided, it is recommended that
a suitable catch pan, adequately drained, be
installed under the water heater.
Required clearances:
There must be a 7” (17.8 cm) clearance between
any object and the rear and sides of the water
heater in the event service is needed. A minimum
8“ (20.3cm) clearance above the water heater
to remove the filter for cleaning and for service
access, and clear access to the front of the water
heater, is recommended. Installations that require 6”
clearance on the sides or rear of the water heater
for earthquake straps are also acceptable. In these
cases, additional clearance must be provided on
the opposite side of the unit to allow for service
access. The hot and cold water plumbing and
electrical connections must not interfere with the
removal of the filters.
If a separate GE Appliances ducting kit is
purchased, additional space is required above
and to the rear of the water heater for installation.
Consult the ducting kit manual for specific
instructions. See GEAppliances.com for details.
Installation Instructions
The location chosen for the water heater must take
into consideration the following:
LOCAL INSTALLATION
REGULATIONS
This water heater must be installed in accordance
with these instructions, local codes, utility codes,
utility company requirements or, in the absence of
local codes, the latest edition of the National Electrical
Code. It is available from some local libraries or
can be purchased from the National Fire Prevention
Association, Batterymarch park, Quincy, MA 02169 as
booklet ANSI/NFPA 70.
POWER REQUIREMENTS
Check the markings on the rating plate of the water
heater to be certain the power supply corresponds to
the water heater requirements.
LOCATION
The water heater and water lines should be
protected from freezing temperatures and high-
corrosive atmospheres. Do not install the water
heater in outdoor, unprotected areas.
Locate the water heater in a clean dry area as near
as practical to the area of greatest heated water
demand. Long uninsulated hot water lines can waste
energy and water. Unit must be installed in a level
location.
NOTE: This unit is designed for any common
indoor installation in a space with at least 700cu.
ft. (19.8cu.m) (example 10’ x 10’ x 7’) including:
garage, utility room, attic, closet, etc. It can be
installed in rooms smaller than 700 cu.ft. (19.8cu.m)
with the installation of a louvered door, or two
louvered sections (one at the top and one at the
bottom of the door or wall for airflow), or a GE
Appliances ducting kit (see GEAppliances.com for
details). Louvers should have 240 square inches
(0.15m2) of open airflow area or greater.
Servicing the water heater requires proper
installation such that the air filter, covers, trim
ring, and front panels can be removed to permit
inspection and servicing. Reference installation
instructions found in this manual.
Attic installations require access stairs and solid
flooring with no exposed floor joists up to the
installation location. Moving the water heater or
other appliances to provide service to the water
heater is not covered under warranty.

CATCH PAN INSTALLATION (If
required)
NOTE: Auxiliary catch pan MUST conform to local
codes.
Catch Pan Kits are available from the store
where the water heater was purchased, a
builder store or any water heater distributor or at
GEApplianceparts.com. The catch pan should be
2” (5.1 cm) minimum larger than the Water Heater
base diameter. To prevent corrosion and improve
Drain Valve access it is recommended that the water
heater be placed on spacers inside the catch pan.
LEAK DETECTION SENSOR &
WATER SHUT VALVE (If equipped)
Follow installation instructions supplied with sensor
(placing sensor vertically against water heater, when
using a catch pan) or flat on floor, otherwise (toward
direction water would naturally drain, such as a floor
drain). For unpainted metal catch pans, make sure
the sensor contacts do not touch the metal directly,
as this can lead to a false water leak alert.
Pair Sensor to water heater by pressing senor
button until sensor light begins blinking. Press the
Accessory button on water heater control until light
above button starts blinking. Once paired, both lights
will blink quickly and then remain solid. After a short
time, the light on the sensor will go off, to conserve
its battery.
Install Water Shut-Off Valve following instructions
packaged with valve.
CONDENSATION DRAIN
CONNECTION
This unit has a condensate drain; therefore a floor
or other drain no higher than 36” (91.4cm) above
the floor must be available in close proximity to the
water heater to allow for the shortest possible drain
line with minimal turns to be installed. Drain must
meet state and local codes. It is important to install
a
3
/4” FNPT fitting suitable for either rigid or flexible
drain line to the primary drain port coming off the
side of the unit. Diameter reductions from a
3
/4” drain
line are discouraged.
Ensure that the rigid or flexible drain line maintains a
downward slope to allow for proper gravity drainage
of condensate to the drain and to allow for proper
function of the condensate drain blockage sensor
(see page 13). If no drain is available, then a
common condensate pump with a capacity no less
than 1 gallon (3.8L)/day must be purchased and
installed. It is important to route the flexible or rigid
drain line so that the discharge water cannot contact
live electrical parts or cause water damage .
Additional parts needed:
1- Flexible 3/4” drain line and associated 3/4”-FNPT
fittings.
(Typical Installation)
THERMAL EXPANSION
If a check valve is present on the inlet water line,
it will create a “closed system.” Heating water in
a closed system creates an increase in pressure
within the water system because the pressure is not
able to dissipate in the main supply line. Referred to
as “thermal expansion”, the rapid pressure increase
can cause the relief valve to operate (releasing
water) during each heating cycle, potentially causing
premature failure to the valve or even the water
heater. The suggested method of controlling thermal
expansion is to install an expansion tank in the cold
water line between the water heater and the check
valve as shown in the following illustrations. Contact
your installing contractor, water supplier, or plumbing
inspector for additional information.

WATER SUPPLY CONNECTIONS
Appliance requires water supply pressure between
20 psi to 125 psi (138 kPa to 861 kPa).
Refer to the illustration below for suggested typical
installation. The HOT and COLD water connections
are clearly marked and are ¾” NPT on all models.
When connecting to the inlet/outlet ports, the use
of ¾”female NPT tapered thread fittings with use of
thread sealant is recommended. The installation of
unions is recommended on the hot and cold water
connections so that the water heater may be
easily disconnected for servicing if necessary.
NOTE: Install a shut-off valve in the cold water
line near the water heater. This will enable
easier service or maintenance of the unit later.
IMPORTANT: Do not apply heat to the
HOT or COLD water connections. If sweat
connections are used, sweat tubing to
adapter before fitting the adapter to the
cold water connections on heater. Any heat
applied to the hot or cold water connection
will permanently damage the internal plastic
lining in these ports.
Install a vacuum relief valve and/or anti-siphon
device when required by local jurisdictions.
TYPICAL INSTALLATION
IMPORTANT: Hot water recirculation loop systems
are not recommended for use with this product.
These systems can reduce efficiency and may lead to
temperature control issues with mixing valve models.
Integrated electronic mixing valve models should not
be installed with pre-heated water from solar or other
heated sources (higher than intended user set point).

Installation Instructions
CAUTION
To reduce the risk of excessive
pressures and temperatures in this water heater,
install temperature and pressure protective
equipment required by local codes and no less
than a combination temperature and pressure relief
valve certified by a nationally recognized testing
laboratory that maintains periodic inspection of
production of listed equipment or materials, as
meeting the requirements for Relief Valves and
Automatic Gas Shutoff Devices for Hot Water
Supply Systems, ANSI Z21.22. This valve must be
marked with a maximum set pressure not to exceed
the marked maximum working pressure of the water
heater. Install the valve into an opening provided
and marked for this purpose in the water heater,
and orient it or provide tubing so that any discharge
from the valve exits only within 6 inches above, or
at any distance below, the structural floor, and does
not contact any live electrical part. The discharge
opening must not be blocked or reduced in size
under any circumstances.
TO FILL THE WATER HEATER
WARNING
Risk of Unit Damage - The
tank must be full of water before heater is turned
on. The water heater warranty does not cover
damage or failure resulting from operation with
an empty or partially empty tank.
Make certain the drain valve is completely closed.
Open the shut-off valve in the cold water supply line.
Open each hot water faucet slowly to allow the air to
vent from the water heater and piping.
A steady flow of water from the hot water faucet(s)
indicates a full water heater.
F75” fault code during installation: If the unit is
powered on without a full tank, the error code “F75”
will show in the display. Turn off the power, fill the
tank with water (see above), then turn the power
back on.
NOTE: The DRY TANK DETECTION feature on tank
is for the aid of installer and should NOT be used
as the primary control to prevent operation with an
empty or partially filled tank. Power should NEVER
be applied to the water heater until installer has
verified tank is filled and all air has been purged from
system.
NOTICE
For maximum heating
performance, apply 240 VAC or 208 VAC across L1
and L2 wires as shown in “Water Heater Junction
Box “ illustration.
If a 4-conductor wire is supplied to the water heater,
cap the neutral, and connect the remaining wires as
illustrated.
NOTE REGARDING UTILITY POWER-
MANAGEMENT DEVICES (Sometimes called Peak
Load Reduction Switches):
Some power-management switching devices or
even some basic timer switches exist that REDUCE
voltage from 240V to 120V during high-electricity-
demand periods. These type of device are allowable
ONLY on 120V convertible models and NOT on
240V non-convertible models.
RELIEF VALVE
WARNING
Risk of Unit Damage - The
pressure rating of the relief valve must not
exceed 150 PSI (1034 kPa), the maximum
working pressure of the water heater as marked
on the rating plate.
A new combination temperature and pressure-relief
valve, complying with the Standard for Relief Valves
and Automatic Gas Shut-Off Devices for Hot Water
Supply Systems, ANSI Z21.22, is supplied and must
remain installed in the opening provided and marked
for the purpose on the water heater. No valve of any
type should be installed between the relief valve and
the tank. Local codes shall govern the installation of
relief valves.
The BTUH rating of the relief valve must not be less
than the input rating of the water heater as indicated
on the rating label located on the front of the heater
(1 watt=3.412 BTUH).
Connect the outlet of the relief valve to a suitable
open drain so that the discharge water cannot
contact live electrical parts or persons and to
eliminate potential water damage.
Piping used should be of a type approved for
hot water distribution. The discharge line must
be no smaller than the outlet of the valve and
must pitch downward from the valve to allow
complete drainage (by gravity) of the relief valve
and discharge line. The end of the discharge line
should not be threaded or concealed and should
be protected from freezing. No valve of any type,
restriction or reducer coupling should be installed in
the discharge line.

Installation Instructions
WHAT TO EXPECT FOR “NORMAL STARTUP” IN HYBRID MODE
After the unit has been installed, with all electrical and water connections secure and checked, then the unit
should be filled with water (vent tank by opening a hot water faucet somewhere in home to allow tank to fully fill
with water). Once tank is full and power is energized, you may experience the following:
Elapsed Time HEWH Actions Comments
0 to 3 minutes Unit will go through self-check. Fan
will turn on after 1 minute.
This 3-minute off-time prevents compressor
damage. A clicking noise may be heard during
startup.
3 to 12 minutes Compressor turns on. Fan continues
to run.
This 9-minute period is used to ensure the tank
is full of water (Dry-fire prevention algorithm). If
no water is detected, a F75 Fault code will be
displayed.
12 minutes and
beyond
Compressor turns off (Fan will run
for 30 minutes after any compressor
operation). Normal heating operation
resumes.
The water heater is operating in Hybrid mode.
Quickly provides initial amount of hot water with
heating elements, then switches to efficient heat
pump for majority of heating.
NOTE: The heat pump operating range is 35°F to 120°F (2°C to 49°C). If the ambient temperature is outside
of this range, the heat pump will turn off and the electric elements will be used until the ambient temperature
returns to within the operating range.

Frequently Asked Questions
Filter:
Q: Why are there Air Filters?
A: In Hybrid and Heat Pump the unit moves air through
the system. Air Filters protects the unit from dirt.
Clean Air Filters improves efficiency.
Q: How to clean the Air Filters?
A: Leave power on and remove Air Filters. Air Filters can
be vacuumed clean or rinsed with warm water. Once
cleaned, reset the alarm by pressing and holding the
Filter button. A dirty filter will reduce water heater
efficiency!
Modes:
Q: What is Heat Pump?
A: Heat Pump is the most-efficient mode. It takes
heat from the air to heat water, thereby cooling the
surrounding air. Slower recovery but most-efficient
mode.
Q: What is Hybrid?
A: The Hybrid mode combines benefits of Heat Pump
with the speed and power of Standard Electric. This
provides great performance with less energy.
Q: What is High Demand?
A: High Demand can be used when hot water usage is
higher than normal. The unit will be less efficient but
will heat water faster in response to long water draws.
For all normal draws, the unit will still use the efficient
Heat Pump the majority of the time.
Q: What is Vacation mode?
A: If you are gone for an extended period, this mode
lowers the water temperature to reduce energy used.
Unit will switch to the previous mode one day before
you get back.
Q: What is Standard Electric?
A: Standard Electric mode uses only the resistance
heaters to heat the water. This gives faster hot water
recovery than Hybrid mode, but uses more energy.
This mode operates without the fan, stopping the cool
air normally discharged during heat pump operation.
Operation:
Q: Why can I hear the unit run?
A: In the most energy-efficient modes, Heat Pump,
Hybrid, and High Demand, the method used to heat
the water uses a fan that can be heard while running.
Q: The heat pump is not running its normal length of
time. What causes this?
A: Under some conditions, the GeoSpring™ Hybrid
Water Heater will operate using the electric elements
instead of the heat pump to protect your unit and
ensure hot water is available to you. These conditions
include extreme cold ambient temperature (<35°F),
extreme hot ambient temperatures (>120°F), or very
low voltage conditions. The unit will return to normal
operation when conditions permit.
Q: Why is one of the operating mode LEDs flashing?
A: In Hybrid Mode and High Demand Mode, the
Standard Electric Mode LED will flash anytime the
heating elements are active, such as during the initial
recovery from a large draw. In Standard Electric
Mode, the operating mode LED will flash after 48
hours as an indication that the unit is not operating
in the most energy efficient mode. These are both
normal conditions and do not indicate an operating
issue.
Q: Why isn’t the temperature setting always displayed on
the control?
A: The display screen will go blank after a period of
inactivity in order to conserve energy. Pressing
any button will wake the control and display the
temperature setpoint.
Anode Rod:
Q: What does an anode rod do?
A: The anode rod provides protection against corrosion
of the water heater tank. The anode rod must be
replaced before it is consumed and no longer offering
protection against corrosion.
Q: How to change the anode rod?
A: Refer to page 15. Models equipped with an anode
depletion sensing feature require a unique anode that
can be ordered through GE Appliances Service.
Q: What can I do about a sulphur smell coming only from
my hot water?
A: Some areas have water conditions that may cause an
odor to develop in the water heater. Aluminum-Zinc
alloy replacement rods are available to address the
condition. See page 14 for details.

Troubleshooting
Before you call for service.
Save time and money! Review the chart below first and you may not need to call for service.
CAUTION
For your safety, DO NOT attempt repair of electrical wiring, controls, heating elements or other
safety devices. Refer repairs to qualified service personnel.
Problem Possible Causes What To do
OPERATION AND PERFORMANCE
Not enough or no hot water Water temperature may be set
too low
• See the Water Temperature Adjustment section (see page 4). If the product
has an integrated mixing valve, turn capacity setting up to “High” or
“X-High” to increase available hot water capacity.
Hot water usage pattern exceeds
the capability of the water heater
in current mode
• Change to different mode.
• Wait for the water heater to recover after an abnormal demand.
Cold water inlet temperature
may be colder during the winter
months
• This is normal. The colder inlet water takes longer to heat.
• Consider increasing the set temperature as described in the Water
Temperature Adjustment section or increase capacity setting on models
equipped with an electronic mixing valve.
Leaking or open hot water
faucets
• Make sure all faucets are closed.
Long runs of exposed pipe, or
hot water piping on outside wall
• Insulate piping.
Not enough clearance to allow
air to circulate for the heat pump
• Make sure unit is 7” away from the wall and has 8” clearance above the air
filter.
Room is too small or too cool,
slowing heating performance
• Smaller rooms can lead to cooler room temperatures due to the heat pump
cooling the air. If the room is smaller than 700cu.ft. (10’x10’x7’), install
louvred doors or similar ventilation.
• Cooler room temperatures can cause the water heater to take longer to fully
recover to the set temperature. Consider increasing the set temperature as
described in the Water Temperature Adjustment section.
A fuse is blown, circuit breaker
tripped, or electric service to
your home may be interrupted
• Replace fuse or reset circuit breaker.
• Contact the local electric utility.
Inadequate wiring • See the Installation Instructions.
Manual reset high limit (ECO) • See the Safety Controls section, see page 5.
Water Connections to unit
reversed
• Correct piping connections.
Dip tube damaged • Contact your local installer, plumbing contractor, or previously agreed upon
service agency.
Recirculating System
Interference (if installed)
• Hot water recirculation systems should not be installed on mixing valve
models
Water is too hot Water temperature is set too
high
• See the Water Temperature Adjustment section.
Electronic Control has failed • Call for service.
Water heater is making the
room cooler
Room is not vented properly or
is too small
• If the room is smaller than 700cu.ft. (10’x10’x7’) then it must have a louvred
door or other means to allow air exchange with surrounding rooms.
Heat is removed from the air to
heat the water
• This is normal.
CONTROL PANEL
The heater is beeping and
the display says F75
The water heater has not been
filled with water before powering
up. Powering up the heater
without water will damage the

heater warranty does not cover
damage or failure resulting
from operation with an empty or
partially empty tank.
• Fill the tank completely with water. Press ENTER to stop the alarm and
then cycle power when the tank has been filled.
• If the unit has been confirmed to be filled with water, and an F75 code is
experienced, it is possible that the code may be a false indicator due to
certain unique environment conditions encountered during the start up. If
the unit is full of water, turn the breaker off for about 10 minutes to allow
the water temperature to stabilize, then turn the breaker back on. If the F75
code persists, schedule GE Appliances Service.
The heater is beeping, the
anode light is on (on some
models), and the display
says F70
The anode rod is approaching
end of life and it is
recommended to replace it
in order to continue to offer

system
• This is an unacceptable condition and must be corrected. See Thermal
Expansion section on page 23. Do not plug the relief valve outlet. Contact
a plumbing contractor to correct this.
Hot water has a rotten egg
or sulfur smell
Certain water supplies with high
sulfate content will react with
the anode rod that is present in
all water heaters for corrosion
protection of the tank
• The odor can be reduced or eliminated in most water heaters by replacing
the anode rod with less-active material rod. In some cases, an added
step of chlorinating the water heater and all hot water lines may be
necessary. Contact your local water professional or plumber for options
and instructions.
Go to GEAppliances.com/waterheater for information on purchasing
this replacement anode rod. A qualified servicer or plumber should do
this replacement. Use of a non-GE Appliances approved anode rod, or
operating the water heater without a GE Appliances approved anode rod
will VOID the warranty.
• In certain cases, increasing the tank temperature to 140°F (60°C) can
reduce this odor issue. Reference the Water Temperature Adjustment
section of the Important Safety Information of this manual for procedure
and dangers of scalding water. Installation of temperature limiting valves
can be used to reduce risk of scalding.
